LUBRIGATING- DEVICE.

Application filed May 28, 1913.

United States, residing at Ludlow, inthe county of Vindsor and State of Vermont, have invented new and useful Improvements in Lubricating Devices, of which the following is a specification.

The invention relates to an improved lubricating device designed primarily for use with car bearings and constructed to continuously feed the oil to the bearing during the rotation of the axle.

Themain object ofrthe present invention is the provision of a casing or box to surround the journal and axle terminal and adapted to receive a predetermined quantity of lubricant, the mechanism arranged with in the box and operated by and during the rotation of the axle serving to direct the contained oil or lubricant on to the axle.

A further object of the invention is the provision of a means to prevent the escape of the oil from the box while at the same time preventing the entrance of dust or other foreign elements.

The invention inits preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is aperspective view of the improvement. Fig. 2 is a vertical central section of the same. Fig. 3 is a perspective view of the dust excluding elements.

In the accompanying drawings, the improvement is shown as applied to a car bearing, the axle 1, bearing 2 and wheel 3, conventionally illustrating the similar appropriate parts of any desired form of such bearing. V

In carrying out the present improvement we provide a casing 4, designed to be secured to the trucks or other part of the structure in any desired or approved manner, the easing being formed in its inner wall with an opening 5 for the entrance of the axle, and inits forward wall with an opening 6, the side and bottom edges of which have longitudinally extending ribs 7 A door or closure 8 is designed to cooperate with the openings 7, being formed on its appropriate edges with channels 9 to receive the ribs 7, the bottoms of the channels being preferably provided with felt strips as 10 to seal the connection. The upper edge of the door is provided with lateral flange 11 designed Specification of Il'ietters Patent.

Serial No. 770,445.

to overlie the upper wall of the casing, the flange being formed with a slot 12 to receive a set screw 13 terminally cooperating with the upper'wall of the casing whereby the door is secured in place. The door may if desired be formed with a side opening 14 protected by a glass covering to permit inspection of the interior of the casing to determine the quantity of oil therein, metallic leaf 15 being arranged to cover the opening and protect the glass at other times.

The bottom of the casing is provided with upstanding bearing posts 16 and 17 the latter of which is formed with a central longitudinally extending bore 18 in which is removably mounted a bearing block 19, through the medium of the stem 20 projecting from the block and loosely fitting into the bore 18. Anagitator is mounted in the post 16 and in the bearing block 19, said agitator comprising a shaft 21 reducedv in diameter to provide bearing portions and fitted intermediate the bearing posts with agitating paddles or blades 22. Beyond the bearing block 19 the shaft 21 is fitted with friction roller 23 designed to engage with the flange 24 of the axle, whereby in the rotation of the axle the agitator is operated. A spring 25 is arranged in the bore 18 of the post 17, said spring acting to normally maintain cooperative engagement between'the friction roller and axle flange under all conditions of travel, whereby to insure a continue-us and uniform operation of the agitator, as will be evident.

In connection with the improved lubricator we provide means for positively sealing the openings 5 of the casing against the escape of oil or the admission of foreign elements. In this connection, we provide a guard disk made up of semi-circular sections 26 each of which is formed with one half of the lateral sleeve extension 27 the disk sections being formed with central semi-circular depression 28 in coincidence with the interior bore of the sleeve extensicn. The respective disk sections when con nected are designed to loosely encircle the shaft, and provide a sleeve extension encircling said shaft and exteriorly threaded at'29. For cooperation with the guard disk we provide a locking disk 30 having a lateral interiorly' threaded sleeve extension 31, the interior diameter ofwhich corresponds to the exterior diameter of the sleeve extension from the guard disk; The locking'disk 30 is provided with a set screw 32 which when the parts are assembled as hereinafter described, will engage and lock the guard disk in place. 7

Coeperating with the guard and locking disks are sealing plates 33 and 34, the former of which has a length corresponding to the interior width of the casing and is designed to seat in the felt packed channel 34 in the bottom of the casing. The upper edge of the sealing plate is formed with a semi-circular depression 36 to fit the lower half of the sleeve 31, the edges of the plate beyond the depressions being formed with a longitudinally extending channel 37. The upper plate 34, which corresponds in size and shape to the lower plate is formed on its lower edge with a sleeve receiving channel 38 and beyond said channel with tenons or ribs 39 to seat in the channels 37 of the lower plate, when said plates are assembled. The channels 37 have packing strips arranged therein, while the axle receiving depressions of the guard disk sections have a felt receiving channel 40, a similar felt re ceiving channel all being arranged on the relatively inner face of the locking disk. The top of the casing is formed with transversely, extending slot through which the sealin g plates are introduced into the casing, and the upper plate is provided with a laterally extending lip 43 to overlie the top of the casing and receive a set screw 4% having threaded cooperation with the casing.

In assembling the parts above descr bed, the locking disk is passed from end of the axle, the sections of the guard disk are passed through the opening 5 in the casing, and the locking disk screwed on to the sec tions of the sleeve of the guard disk to hold the parts connected. The plates 33 and 34 are inserted through the slot 42 and the locking disk then screwed up until the plates are more or less closely confined between the locking and guard disks. An effective seal fo the opening 5 is thus provided, which will absolutely prevent the escape of oil while at the same time excluding the entrance of dust or other foreign matter into the casing.

During operation of the axle the oil naturally gravitating to the bottom of the casing, will be thrown against the axle by the agitating plates, thus keeping the axle at all times properly lubricated. hen an inspection of the interior of the casing determines the necessity for an additional oil supply, the latter may be delivered through the opening in the casing provided for the recept on of the set screw 13.

hat is claimed is l. A casing formed with an axle opening, spaced disks surrounding the axle within the casing and removably secured together and sealing plates arranged between said disks to close the space between the casing on opposite sides of said plates against each other, said casing being formed with a slot to permit the insertion of said plates.

2. A casing formed with an axle opening, spaced disks surrounding the axle within the casing and removably secured together, sealing plates arranged between said disks to close the space between the casing on opposite sides of said plates against each other, said casing bein formed with a felt packet recess to receive one edge of one of said plates.
